3sqrt(8)-sqrt(8x^3+71)=0

38 - 8 x^{3} + 71 = 0

x = \frac{1}{2}

Decimal Notation

x = 0.5

Solution steps

38 - 8 x^{3} + 71 = 0

Expand

38 - 8 x^{3} + 71 : 62 - 8 x^{3} + 71

62 - 8 x^{3} + 71 = 0

Move

62

to the right side

- 8 x^{3} + 71 = - 62

Square both sides:

8 x^{3} + 71 = 72

8 x^{3} + 71 = 72

Solve

8 x^{3} + 71 = 72 : x = \frac{1}{2}

x = \frac{1}{2}

Verify Solutions:

x = \frac{1}{2}

True

The solution is

x = \frac{1}{2}

x - 3 = x

x - 6 = x + 6

1.2 x = 8 x^{0.12}

2 = 3 u - 12 - 1

x, y^{2} = x - 1
